I'm getting ready to install a trick flow intake manifold on my 94 GT. I was looking at the new lower intake the other day and noticed a few threaded holes near the front and rear of the manifold. I don't remember taking any kind of connection off of my manifold when I removed it, but I may have. I was wondering if these holes were for sensors, or if they only apply to 88-93 mustangs because the manifold will work for both. If anyone knows i'd appreciate the help. Thanks.

Are you refering to the screws for the fuel line on both sides one set is up front the other is in the rear?

You know what, that never even crossed my mind. I bet that's what they are, but the are rather large, about 3/4" or so, are the screws you're reffering to about this size, or are tehy smaller?

i have the same manifold and its okay...they're supposed to be there. I noticed that when i put mine on.

What went into those holes stanger? Did you have a use for them, or did you plug them up or just leave them alone?

if we're talking about the same ones, i believe they're for o2 sensor's. U have to screw them in and put some silicon around the threads so its super-tight!.
